The Save / Log Segment menu function creates a backup version of the oldest completed log segment. After successful termination of the backup operation, the log segment is cleared.
Log segments can be saved in WARM and in COLD mode. The backup of log segments must be performed in adequate time intervals (e.g., daily). It is recommended to use Options / Autosave Log to save a log segment automatically as soon as it has been completed.
For configurations without log segments, the Save / Log Segment menu function is only provided in COLD mode. In this case, the whole log is saved as one segment and the log is cleared after successful termination of the backup.
If a log should become full in an operative serverdb, the serverdb shuts down automatically. In this case, CONTROL can only reach the WARM mode after performing Save / Log Segment in COLD mode. CONTROL recognizes such a situation and automatically suggests this action.
